Judging by their posture and non verbal communication I'd say there are 2 distinct personalities there. The blue is more reserved of the pair. The purple is the more aggressive and self assured of the two and more of a risk taker. The blue, while not totally shy is also somewhat self assured but not nearly to the extent of the purple. The blue is more reserved and thoughtful and likely to be able to get along by herself. The purple is more out going and expressive, a definitely more socially oriented than the blue. I'd say the blue likes quiet times more than the purple who is more of a "party" or activity driven.
This is interesting HT, what were you after here? It's obvious that the photo was taken in the Slavic area of the world. The "babushka" and the cyrillic writing as well as the small panel van indicate it's definitely not in the America side of the globe.
